Lecounte appeals his convictions of armed robbery and simple battery. Held:
1. The appellant complains that during the call of the calendar, the district attorney made a prejudicial reference to certain prior conduct on the part of defense counsel. However, the record reveals that defense counsel declined the opportunity either to examine the prospective jurors on this issue or to have corrective instructions given to the jury. "In order to warrant the grant of a mistrial, there is a burden of showing not only error but prejudice." Kennedy v. State, 179 Ga. App. 587
, 592 (4) (347 SE2d 604
) (1986). The appellant's motion for mistrial was properly denied.
2. The appellant further contends that the state's case was based on the uncorroborated testimony of an alleged accomplice. However, it appears from an examination of the transcript that the testimony of the accomplice, Stewart, was corroborated in several respects. In particular, there was testimony that a ski mask was found in front of the trailer in which the appellant resided; and a police detective with a background in "tracking" identified a footprint found at the crime scene as being similar to the pattern on a tennis shoe found in the appellant's trailer.
